I've ordered from EBTH several times now and would just say to be very careful about how you bid. Unlike every other auction platform, they have two fields: Current Bid and Maximum Bid. If you enter a bid in Current Bid, it immediately raises the price to that bid. I can't figure out why a bidder would ever want to use that option, which is what auction houses and platforms figured out a long time ago and why every platform simply raises the bids at regular increments and uses proxy or absentee bidding to bid automatically for you at regular increments. But in any event, it tricked me and cost me $ 300 over the going rate of the item. My fault I suppose, since I did have that as my top bid in mind, but frankly I was expecting a fair auction and not to have to read fine print on the basic operation of bidding.
As a side note, their customer service was TERRIBLE whenever I reached out about the issue I had.
